ah, then I think you should postpone it from deviant art immediately and check with the company if you can put it in your portfolio. I thought you had permission to use it since it was on here. I understand how something as simple as posting it on here could be damaging to your carrier and status as an employee or freelancer.
I wanted to post the office art for critique, but Jon was like "LOL no". I was told we were able to keep up the stuff we had prior to you know who, but after that everything was copyright to them and needed permissions. At least that's my understanding of it.
